United Kingdom and the Eurozone

United Kingdom and the Eurozone DEFINITION OF CURRENCY UNION In the world today, systems in which countries come together in agreement of sharing single money. The system is called currency or monetary union, its importance and number of participants is growing. In May 2005, 52 out of 184 IMF members participated in currency unions (Rose, 2006). A currency union can be defined as a system where two or more groups usually countries share a common or single currency in order to keep the value of their currency at a certain level (Investopedia, 2015). It can also be defined as an agreement among member’s countries or other jurisdictions to share a common currency, and a single foreign and monetary exchange policy (Rosa, 2004). Currency unions occur when a poor country unilaterally adopts the money of a larger â€Å"anchor† country. For Example, a number of countries currently use the American dollar such as Panama, Ecuador, and a number of smaller countries and dependencies in the Caribbean and Pacific (Rose, 2006). In Africa, Swaziland, Lesotho and Namibia all use the South African Rand thereby forming a currency union (Multilateral monetary area). In these cases, the exchange and interest rates of dependent countries are influenced and determined by the anchor country, generally in the interest of the anchor. There are a number of multilateral currency unions between countries of similar size and wealth such as the East Caribbean dollar: Anguilla, Antigua and Barbuda, Montserrat, Grenada, Saint Kitts and Nevis, Saint vincent and the Grenadines and Saint Lucia. The Central Bank of the West African of the CFA franc: Benin, Burkina Faso, Guinea-Bissau, Mali, Niger, Senegal and Togo and also the Bank of the Central African States. Other currency unions in the world are the monetary authority Singapore, eastern Caribbean currency union, multilateral monetary area etc. The largest currency union is the Economic and Monetary Union of the European Union which began on the 1st January 1999, although the euro was only physically introduced three years later. Twelve countries instituted the euro as a legal tender, delegating and determining monetary policy for EMU to through the international European central bank. One of the reasons of forming a currency union is mainly to synchronize and manage each member countrys monetary policy which could be done through lowering of transaction costs of cross-border trade (Silva and Tenreyro, 2010) The union is expected to grow more with Cyprus, Malta, Slovakia and Slovenia recently joining the area and other states such as Monaco, San Marino and Vatican City unilaterally adopting the euro as their sole currency however, Sweden, Iceland, Denmark and the United Kingdom have rejected membership but maintained debates on the advisability of adopting the euro particularly after the onset of the global financial crisis (Carney, 2014). Currency unions have no definite size therefore there is no appropriate domain for a currency. The use of a single or common currency is advantageous to regions as well as can also cause problems in the dual presence of asymmetric shocks and nominal rigidities (in prices and wages) (Mundell, 1961). The effect of the size on currency union tend to create more open and fewer nominal rigidities for smaller countries making them better candidates for currency unions (Mckinnon, 1963). The effects of the economys degree of diversification could result in fewer asymmetric shocks and accordingly fewer benefits from national monetary policy. The insights of the theory of optimum currency areas provided by Mundell (1961) concluded that common currency areas are defined by internal mobility and external immobility of factors of production. According to this theory, the optimum size of currency area depends on the tradeoff between the macroeconomic efficiency gains and micro-economic costs. The forming currency unions have its costs as well as benefits. THE COSTS Generally, the main cost of joining a currency union is the loss of an independent monetary policy with the inability to react to shocks through exchange rate adjustments. Monetary independence can be beneficial when shocks are regionally specific, alternative mechanisms are weak and when exchange rate changes function as means of lightening idiosyncratic shocks Countries that could potentially let their exchange rates adjust to justify the impact of shocks often display fear of floating and thus do not exploit the automatic stabilization properties of exchange rates (Calvo and Reinhart, 2002). Countries reluctance to implement monetary policy to tackle shocks could be linked to its actual effectiveness; less effectiveness of monetary policies to facilitate the adjustment or possibly wider consideration such as fear that it may trigger beggar thy-neighbor responses by trading partners inducing structural volatility in the financial markets. Besides the absence of price adjustment mechanisms, output stabilization and currency revaluation in the currency union faces another challenge. A system of income transfers is necessary for softening negative asymmetric shocks in countries that have joined a currency union however; the prospect of income transfers between countries generates the type of moral hazard commonly seen in insurance models (Grabner, 2003). Another cost of currency unions relate to overcoming structural differences among the countries. The transition towards a monetary union is likely to expose structural weaknesses (Jacquet 1998 and Grabner 2003). By entering a monetary union, countries lose the ability to correct their monetary troubles in short term. The necessary structural reform preceding the acceptances of a single currency focus on issues like taxation, supervision of capital markets and also mutual recognition and harmonization of labor markets (Jacquet 1998). There is also an issue of fiscal financing. Public budget can be financed from government bonds and tax revenues. A country in a currency union is likely to face constraints on financing options resulting in a suboptimal situation. At the same time, government bonds are linked to inflation and a currency union implicitly assumes convergent optimal inflation rates (Grabner 2003). In reality the optimal levels of inflation may differ among the countries in the currency union. Furthermore, the cost or problem of currency union inability of participant countries to independently choose an inflation rate. It seems relatively less important now than in the past as improvements in available technology to central banks enable sustainable inflation that result in low actual inflation rates in most countries however if a country plagued by low productivity enters a currency union of higher productive countries, it could experience higher inflationary rates (Coleman 1999). THE BENEFITS One of the main benefits of currency unions envisaged by Mundell (1961) is the elimination of currency conversion costs and greater predictability of prices which would increase trade. The savings are more significant for small, open and less developed countries whose currencies are not used for international payments (Grabner 2003). Coleman (1999) mentions the savings from the reduction of transaction costs and reduction of price uncertainty together account for 0.4 percent of GDP in the Eurozone. Increased price transparency and reduced price uncertainty are often quoted as interrelated benefits of currency unions. The reduction of price uncertainty is linked to the use of unit of account which is simultaneouslu used by broader economic area (Zika, 2006). The even disappearance of exchange rates removes a vital barrier to trade integration; this furthermore leads to better information, increased competition and price transparency (Jacquet 1998 and Grabner, 2003). Further benefit of monetary union is the removal of competitive devaluations by member countries which also known as â€Å"beggar-thy-neighbor† policy (Kronberger, 2004). Within currency unions, both importers and exporters have a strong interest in avoiding disproportionate swings in exchange rates. The transfer of resources between regions by the centralized monetary authority through its money issuing function. These transfers can be used to diversify the risk of expected economic shocks however; public finance plays a significant role (Voss, 1998). Currency union has the potential to reduce the number of investment failures. Price uncertainty negatively impacts the welfare or risk adverse individuals in standard economic theory. The greater exchange rate volatility tends to impair the quality of decisions about investment projects abroad; therefore greater exchange rate volatility implies more frequent investment failures and larger costs (Grabner, 2003). Higher risk caused by the increase in price and exchange rate uncertainty increases the real interest rate. Higher real interest rates then highlight the problems of moral hazard and adverse selection. This therefore helps lower systematic risk (Grabner, 2003). Finally, the vast economic area of currency unions increases the effect of networking. The adoption of a single currency in a bigger economic area creates greater benefits for all users. Looking at the economic structure of the United Kingdom and Eurozone, both have projects which are suitable to the individual development and growth of both economies. The United Kingdom becoming a member of the eurozone will be more of disadvantage than benefit to the United Kingdom due to several reasons. The core argument for entering the EMU is the elimination of exchange risk against the euro which would promote much more trade with and within Europe by merging the rather risky and limited sterling capital market into a bigger and less risky euro capital market. The joining of the Eurozone is not to world currency but a regional one. Outside of Europe, most of the world either uses the dollar or is tied to it in some way therefore trade and investment would be half with the euro area and half with the dollar area. But over the years, euro/dollar exchange rate has been highly variable which when compared to British pound/dollar exchange rate it doesn’t seem convincing. If the UK remains outside, the pound can go between the two currencies as the euro swings occur against dollar thereby sitting on the middle of a seesaw. Looking at this, there is no necessary gain in the exchange risk reduction in UK joining the Eurozone and that it is even possible that the overall risk would rise. The benefit of price transparency and comparison between UK and Eurozone is also of little importance in the sense that United Kingdom has no land borders with the Eurozone unlike Belgium and Netherlands. Given this fact, the comparing of prices between both zones is irrelevant. In terms of bailout and the emerging state pension crisis, growth and development is slower than expected while unemployment is turning out to be higher. The politics of pension cut benefits is speculative given that the aging population will increasingly be dominated by older voters. The effect of raising taxes further would lower growth and increase unemployment. It is a matter of concern to the UK that cost of meeting explosive financial liabilities might somehow impact British taxpayers. In conclusion, the reduction of transactions cost of currency exchange would be roughly offset by the one-off cost of currency conversion. There would be some gain from eliminating exchange risk against euro but this would be offset largely by the volatility against the dollar with around half our trade broadly defined with countries either on or closely linked to the dollar. Generally, the exchange risk does not appear to have an important effect on trade or foreign investment, and in the UK case, on the cos of capital. Honestly, I would like to advice that the UK waits and properly assess and plan out different projects. Due to the structure of the Eurozone, I am strongly against the UK joining the Eurozone which is the best interest of British citizens REFERENCES A Coleman.

Developing And Conducting A Successful Capital Campaign Essay -- Fund-

Developing And Conducting A Successful Capital Campaign A capital campaign is an effort to raise funds for the capital needs of an organization or institution. This includes acquisition of property or equipment, construction, renovation, endowments, special projects and programs. Capital campaigns are an occasional necessity, from time to time, in the life of an institution especially when it is part of an institution’s master or long-range plan. The efforts of a capital campaign are of major proportions usually taking place over several years. The reason I have undertaken the research of developing and conducting a successful capital campaign is because I have been in environments where capital campaigns were being conducted. As an undergraduate at Cal State Dominguez Hills, I recall the ground breaking of the Loker Student Union, which was in the last phase of its campaign. I also remember when the campus took on the task to raise fund for the Challenger Center; it was considered in the pre-public phase of the campaign. As a professional, I have been fortunate to be part of two capital campaigns, UCLA’s and the Greater Los Angeles Zoo Association’s. In 1993 at UCLA, I was an assistant to the Director of Development of the Neurosciences in the School of Medicine. Along with the other campus schools, I was involved in the planning and preparation that occurred before the capital campaign called the pre-public phase. It was a very educational experience that I enjoyed. In 1997/98, as a Manager of the Capital Ca mpaign at the Greater Los Angeles Zoo Association, I was involved in efforts during the capital campaign called the public phase. While my experience at the Zoo was also education, I realized that components of the ca... ...le to exceed its goal. BIBLIOGRAPHY Capital Ideas, by M.

Experiment 1: Calorimetry

Experiment 1: Calorimetry Nadya Patrica E. Sauza, Jelica D. Estacio Institute of Chemistry, University of the Philippines, Diliman, Quezon City 1101 Philippines Results and Discussion Eight Styrofoam ball calorimeters were calibrated. Five milliliters of 1M hydrochloric acid (HCl) was reacted with 10 ml of 1M sodium hydroxide (NaOH) in each calorimeter. The temperature before and after the reaction were recorded; the change in temperature (? T) was calculated by subtracting the initial temperature from the final temperature. The reaction was performed twice for every calorimeter. The heat capacity (Ccal) of each calorimeter was calculated using the formula, C_cal=(- H? _rxn^o n_LR)/? T[1] where ? Horxn is the total heat absorbed or evolved for every mole of reaction and nLR is the number of moles of the limiting reactant. The ? Horxn used was -55. 8kJ per mole of water while the nLR was 0. 005 mole. Table 1. Average Ccal from recorded ? T values. Trial?

After calibration, a reaction was performed in a calorimeter by each pair. A total of eight reactions were observed by the whole class. The temperature before and after the reaction were recorded. Then the change in temperature was calculated. Eac h reaction was performed twice to produce two trials. The experimental ? Horxn for each reaction was solved using the formula, H? _rxn^o=(-C_cal ? T)/n_LR [2] where Ccal is the heat capacity previously calculated for each calorimeter. The percent error for each reaction was computed by comparing the computed experimental ? Horxn to the theoretical ? Horxn using the formula, % error=|(computed-theoretical)/theoretical|? 100% [3] Table 2. Comparison of calculated ? Horxn and theoretical ? Horxn. RxnLRTrial? T, (oC)?

Horxn as shown by the percent error for each reaction (table 2). The discrepancies were caused by many factors. One factor was the loss of heat. The heat may have bee n released when the thermometer was pushed or pulled during the reaction. The heat may also have been lost because the calorimeter is not totally isolated. Another factor was the dilution of the solution. The pipette or test tube may still have been wet when used. However, the concentration used in solving for values was the concentration of the undiluted solution. Another factor that may have contributed to the difference in the experimental and theoretical values was human error. It was manifested when reading the thermometer or measuring chemicals with different instruments. The factors aforementioned are the limitations of this experiment. References Petrucci, R.

First, heat might have been lost to the surroundings. This is possible whenever the thermometer is pulled out or pushed in the calorimeter during the reaction. Also, the calorimeter might not have been thoroughly isolated. Second, the solution might have been diluted in the test tube or pipette. They might have been wet when used with the solution. Lastly, the discrepancies might have occurred due to human error. The students might have misread the thermometer when taking the temperature or the pipette when measuring the solutions. a. It is important to keep the total volume of the resulting solution to 15ml because any more or any less than that of the volume can contribute to the absorption or release of additional heat therefore affecting the ? Horxn. b. It is important to know the exact concentrations of the reactants to solve for their number of moles and to find out the limiting reactant. c. It is important to know the exact weight of the metal solids used to solve for their number of moles and to find out whether one of them is a limiting reactant. Also, the weight is needed to solve for the heat capacity of the solid when the specific heat is given. 200ml 0. 5M HA + NaOH ? -6. 0kJ LR: HAnLR= 0. 1mole H? _(rxn,mol)^o= (-6. 0 kJ)/(0. 1 mol) ?( H? _(rxn,mol)^o= -60 kJ) HA is a strong acid.

Estacio Institute of Chemistry, University of the Philippines, Diliman, Quezon City 1101 Philippines Results and Discussion Eight Styrofoam ball calorimeters were calibrated. Five milliliters of 1M hydrochloric acid (HCl) was reacted with 10 ml of 1M sodium hydroxide (NaOH) in each calorimeter. The temperature before and after the reaction were recorded; the change in temperature (? T) was calculated by subtracting the initial temperature from the final temperature. The reaction was performed twice for every calorimeter. The heat capacity (Ccal) of each calorimeter was calculated using the formula, C_cal=(- H? _rxn^o n_LR)/? T[1] where ? Horxn is the total heat absorbed or evolved for every mole of reaction and nLR is the number of moles of the limiting reactant. The ? Horxn used was -55. 8kJ per mole of water while the nLR was 0. 005 mole. Table 1. Average Ccal from recorded ? T values. Trial?

After calibration, a reaction was performed in a calorimeter by each pair. A total of eight reactions were observed by the whole class. The temperature before and after the reaction were recorded. Then the change in temperature was calculated. Eac h reaction was performed twice to produce two trials. The experimental ? Horxn for each reaction was solved using the formula, H? _rxn^o=(-C_cal ? T)/n_LR [2] where Ccal is the heat capacity previously calculated for each calorimeter. The percent error for each reaction was computed by comparing the computed experimental ? Horxn to the theoretical ? Horxn using the formula, % error=|(computed-theoretical)/theoretical|? 100% [3] Table 2. Comparison of calculated ? Horxn and theoretical ? Horxn. RxnLRTrial? T, (oC)?

Horxn as shown by the percent error for each reaction (table 2). The discrepancies were caused by many factors. One factor was the loss of heat. The heat may have bee n released when the thermometer was pushed or pulled during the reaction. The heat may also have been lost because the calorimeter is not totally isolated. Another factor was the dilution of the solution. The pipette or test tube may still have been wet when used. However, the concentration used in solving for values was the concentration of the undiluted solution. Another factor that may have contributed to the difference in the experimental and theoretical values was human error. It was manifested when reading the thermometer or measuring chemicals with different instruments. The factors aforementioned are the limitations of this experiment. References Petrucci, R.

First, heat might have been lost to the surroundings. This is possible whenever the thermometer is pulled out or pushed in the calorimeter during the reaction. Also, the calorimeter might not have been thoroughly isolated. Second, the solution might have been diluted in the test tube or pipette. They might have been wet when used with the solution. Lastly, the discrepancies might have occurred due to human error. The students might have misread the thermometer when taking the temperature or the pipette when measuring the solutions. a. It is important to keep the total volume of the resulting solution to 15ml because any more or any less than that of the volume can contribute to the absorption or release of additional heat therefore affecting the ? Horxn. b. It is important to know the exact concentrations of the reactants to solve for their number of moles and to find out the limiting reactant. c. It is important to know the exact weight of the metal solids used to solve for their number of moles and to find out whether one of them is a limiting reactant. Also, the weight is needed to solve for the heat capacity of the solid when the specific heat is given. 200ml 0. 5M HA + NaOH ? -6. 0kJ LR: HAnLR= 0. 1mole H? _(rxn,mol)^o= (-6. 0 kJ)/(0. 1 mol) ?( H? _(rxn,mol)^o= -60 kJ) HA is a strong acid.

When The Average Person Thinks Of Qualities That Describe

When the average person thinks of qualities that describe a good engineer, they might think of qualities such as intelligence or technical adeptness. Qualities such as these do in fact make an engineer good at their job, but they don’t necessarily make them a good engineer. Engineering ethics defines the qualities that create a good engineer as virtues. Virtuous engineers seek high moral standing and fulfillment in their careers beyond that of just solving engineering problems for money. Virtues in this context are qualities or traits of an engineer that not only allows them to excel at their job but also attain fulfillment and happiness. Engineering ethics may be a relatively new field of study but the concepts, on which it is built, such†¦show more content†¦Virtues of thought are traits of the mind that promote intellectual well-being and aid in the pursuit of knowledge, truth, or understanding. In contrast, virtues of character are qualities or traits that help one fulfill their physical goals, or as Aristotle calls them, passions, in a manner that reflects high morality. Both virtues of character and mind can be examined as the perfect middle ground between vices of deficiency and excess. Pride, for example is virtue that is good in moderation. In excess, pride becomes hubris, which led to the fall of many epic characters. In deficiency, pride becomes shamefulness, which can be taken advantage of. Considering all that I have learned so far, do I believe myself to be a virtuous person? Am I capable of becoming a virtuous engineer? The short answer is yes. My upbringing combined with traits I practice and instilled with myself has afforded me many qualities that I, in agreement with ancient philosophers’ text, deem to be virtuous. As far back as I can remember, my parents never wasted a teaching opportunity. Although back then I didn’t appreciate it, the chores, homework, and even confiscation of video games were all tools to develop virtues. Completing chores, despite sometimes requiring increasingly angry reminders, developed discipline as well as respect and appreciation of my surroundings.
